The following describes the embodiments of the present invention further with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and are not intended to limit the scope of the present invention.
Fig. 1 is a schematic flow chart of a synchronous group control method according to an embodiment of the present invention; fig. 2 is a schematic diagram of an application scenario of a synchronous group control method according to an embodiment of the present invention; the synchronous group control method can be used for a PC (Personal Computer ) end; as shown in fig. 1, the synchronous group control method may include:
s110, running window examples corresponding to the mobile terminals respectively.
Specifically, if the PC side is connected to a plurality of mobile terminals, the PC side will operate window instances corresponding to the mobile terminals. The mobile terminal may be a smart phone or other device.
Such as: the plurality of mobile terminals comprise a mobile terminal 1, a mobile terminal 2, a mobile terminal 3 and a mobile terminal 4, and examples of windows operated by the PC end include: window example 1 corresponding to mobile terminal 1, window example 2 corresponding to mobile terminal 2, window example 3 corresponding to mobile terminal 3, window example 4 corresponding to mobile terminal 4.
S120, determining a main control window example and one or more auxiliary window examples for realizing synchronous group control from the window examples.
Specifically, the main control window instance is used for realizing a main control function and receiving and broadcasting user control data; the secondary window instance is used for realizing a synchronization function, and after receiving user control data, the secondary window instance sends the user control data to respective mobile terminals.
When determining the main control window instance and the auxiliary window instance, the method can be determined according to actual conditions, can be determined according to a certain rule, and can be determined according to the specification of a user.
Such as: one window example can be selected randomly from all window examples to serve as a main control window example, and one or more window examples can be selected randomly from the rest window examples to serve as auxiliary window examples.
And S130, when the main control window instance receives the user control data, the main control window instance transmits the user control data to the corresponding mobile terminal, broadcasts the user control data to each auxiliary window instance, and transmits the user control data to each corresponding mobile terminal through each auxiliary window instance.
Specifically, the master control window instance is used for realizing a master control function and can receive and broadcast user control data.
After receiving the user control data, the main control window instance sends the user control data to the corresponding mobile terminal on one hand, and broadcasts the user control data to each secondary window instance, and each secondary window instance sends the user control data to the corresponding mobile terminal, so that the mobile terminal corresponding to the main control window instance and the mobile terminal corresponding to each secondary window instance can both receive the user control data, and the time delay of receiving the user control data by the main control window instance and the mobile terminal corresponding to each secondary window instance is very small (about 40ms to 50ms, which can be ignored for users), thereby realizing the low-delay synchronous group control function.
In an exemplary scenario, as shown in fig. 2, the system includes a PC side (Windows operating system), a mobile terminal 1 (android operating system), a mobile terminal 2 (android operating system), a mobile terminal 3 (android operating system), and a mobile terminal 4 (android operating system).
When the synchronous group control method is executed, the PC end runs a window example 1 corresponding to the mobile terminal 1, a window example 2 corresponding to the mobile terminal 2, a window example 3 corresponding to the mobile terminal 3 and a window example 4 corresponding to the mobile terminal 4. If the window instance 1 is determined as the main control window instance 21, the window instances 2, 3 and 4 are determined as the auxiliary window instances 22, so that the window instance 1 is used for receiving user manipulation data (such as a mouse, a keyboard and an input method in fig. 2), when the window instance 1 receives the user manipulation data, the window instance 1 sends the user manipulation data to the corresponding mobile terminal 1, broadcasts the user manipulation data to the window instances 2, 3 and 4, and sends the user manipulation data to the corresponding mobile terminal 2 by the window instance 2, sends the user manipulation data to the corresponding mobile terminal 3 by the window instance 3, and sends the user manipulation data to the corresponding mobile terminal 4 by the window instance 4, so that synchronization among the mobile terminal 1, the mobile terminal 2, the mobile terminal 3 and the mobile terminal 4 is finally realized.

And if the master control window instance is recovered to the function which can be realized by the common window instance after the master control function is closed or after the auxiliary window instance is closed to the synchronous function: the interface of the corresponding mobile terminal can be displayed, and the individual control of the user on the mobile terminal can be executed.
Further, on the basis of the above method embodiment, the setting rule in the above (1-1) may include: the first window instance to start running is taken as a main control window instance, and other window instances are taken as auxiliary window instances.
According to the embodiment, the main control window instance and each auxiliary window instance can be determined from the window instances according to the set rule, the main control function of the main control window instance and the synchronization function of the auxiliary window instances are started, so that the main control window instance is used for receiving and broadcasting user control data, meanwhile, the auxiliary window instance can also send the received user control data to the corresponding mobile terminal, the accuracy of synchronous group control is improved, the individual requirements of different window instances are met through the operation of the starting function, and the effect of 'instant-on-instant' of different window instances is achieved.
